were you anywhere remotely close to a full gallon in 8 minutes?
I'm not trying to discredit you, it's more for my knowledge with how you're saying how quiet it is, because by rough calculations at the speed you were turning with that current you should have only seen roughly .3-.4 gallons in that time frame that mine will push a full gallon. It gives me good hope that once I slow this thing down a bit she'll be nice and quiet.\
Ideally I'm trying to get mine down to about 10% speed, which will give me round about 25rpm on the pumpheads, and allow me to do longer slower water changes throughout the day. Right now I run for 8 minutes while I'm at work and that's it, one shot and it's done.
